KEF R3 Bookshelf Loudspeakers Review

March 14, 2020 § Leave a comment

“The R3 are 3-way bass reflex speakers with the following compliment of drivers: 1 – 6.5′” aluminum composite woofer, and a 12th generation version of KEF’s venerable Uni-Q driver array. The Uni-Q is KEF’s combination midrange and tweeter driver, consisting of a 5.25″ midrange driver, paired with a 1″ aluminum “Tangerine Wave Guide” dome tweeter residing in its center. The Uni-Q driver design is unique in that it allows the midrange and high frequency bands to speak together with one unified voice, giving music a more natural, lifelike presentation. 15-180 watts of amplification is recommended. The R3 is 87dB efficient with a 38Hz – 50kHz frequency range on paper, although my ears tell me it reaches as low as 40Hz. Relatively easy to power with a 4 ohm impedance rating, minimum 3.2 ohm, I had no trouble driving the R3 to ear splitting levels with a 100 watt per channel NAD M10 currently in for review. As mentioned above, the R3 are rear ported and include a set of foam “bungs” used to help tune the bass as desired, based on room conditions and taste. The R3 also come with high quality bi-wireable binding posts. In fact, everything about these speakers is high quality, from the look, feel, build quality, and finish to the packaging. Naturally none of this would matter unless they also sounded as good as they look and happily they do.”
